First Claim
1. A needle magazine for storing and dispensing a plurality of needle assemblies for use on an injection device having a housing accommodating a cartridge containing medicine for a number of dosed injections and which needle magazine can be carried on said injection device, said needle magazine comprising:
- a plurality of confinements each containing a needle assembly having a first distal end, which is sharpened for piercing the skin of the user and an opposite proximal end and a side wall there between, said confinements each having a first distal surface and an opposite proximal surface, a shell connecting said confinements side by side, and means for supporting each needle assembly in an upright position, having said first distal end pointing towards said first distal surface and said opposite proximal end pointing towards said opposite proximal surface, Characterized in that Said shell can be rotated in order to index said needle assemblies and to position one of said needle assemblies above said cartridge, and that said shell can be activated for bringing said proximal end of said positioned needle assembly into contact with said cartridge, and said distal end of said needle assembly into a position where said distal end of said needle assembly is located outside said magazine, whereby said medicine can be injected.
